* My naive geometric map interpretation is replaced with most widely used Transverse Mercator projection. It is the only projection supported as of now. If projection params are missing in calibration, TB fallbacks to UTM. For some grids, the params are not explicitly shown in calibration, but their support is hardcoded; these are: British National and Swedish grid.
* Via JAD, any geodetic horizontal datum may be added to TB. See trekbuddy.jad for example how to define a datum and map it to name used in calibration. By default, TB knows WGS 84, RT 90, OSGB 36 and S-42 (Russia).
* "mapless view" (aka HPS) is walking direction oriented, with compass on the background. I'm not sure whether it is better to have big pale compass on background or small bright one in a screen corner (right-top)?

There are other small changes/improvements you may or may not notice... If you feel like testing TB, go ahead and let me know how it goes!

hegi - I could not reproduce .loc files parsing problems; revised XML parser anyway - can you try it now?
A780 - I fixed a bug in Settings form and added more diagnostics to Info form; map scrolling may work now (try touching near screen margins)

- bugfixes in HPS (also: new option in Settings for wpt azimuth)
- remapped keys for atlas ops ("*", "#" -> "7", "9") and HPS (use "#" now) - I find "#" more convenient for opening HPS which is more frequent action then atlas ops; sorry but you'll get used to it
- subtle changes in Settings
- smoother map-boundary crossing within atlas
- more fixes in A780 version

And... the pain is over for most of us.... TrekBuddy is now signed... so backup your tar-ed map packages, and then - unpack them!

Once you install the new version (you have to do it via/with JAD), do not forget to set the permissions for the midlet properly ("Read/Write user data: Never ask", or whatever it is on your phone). Also, disable map caching - it is no longer needed!

If you want/need to use in-jar maps, just do not use JAD, or remove MIDlet-Jar-RSA-SHA1 and all 3 MIDlet-Certificate-n properties from it.

I treid new version, and my scanned maps works now :) But IMG maps exported via mapedit show wrong position (lat/long projection). How to define this projection in TB? Ozi puts "Projection Setup,,,,,,," only.

Just tried it. - Unfortunately there is no change!

I just had a quick walk down the street ...
This is *REALLY* great. - I Just love it!

But: is there a way to leave HPS mode and get back to the world-map? - Havn't figured this one out yet.

Do I understand the idea of the short-term (green) and the long-term (cyan) position in this way, that this a position averaging, and that, when I stay at a point for some while, this should home in with greater accuracy ... where the ideal would be all cyan circles in one place = greatest possible accuracy?

By the way: Is there a way to figure somehow more precisely, how accurate my signal is? - Something like inacuracy in meters or so ...?

However, there are things I don't understand - bug?
- World Map doesn't center on current position (leading to red coordinates - with correct current position)
- I don't really understand what is the logic for the suggested default for "enter waypoint manually"? - Sometimes it appears to be current position. Then again it seems to be the position when changing map-mode last time ... I find this confusing.

I noticed something strange yesterday (31.12). When i start receiver, i've got fix, but without UTC time. TB don't know what to do, and can't connect to receiver, mobitrack demo works, but show only position and speed, no utc, track, stats.

chrysanthemumman: just change the extension from .zip to .jar, I guess it has something to do with server settings

krzysiekz: don't you happen to have NMEA log? and, I've added support for "Latitude/Longitude" projection; your map worked well for me (see 0.9.5b4)

hegi
[list]- LOC parsing is a mystery to me ; anyway, put some more checks in the code, so if you would try 0.9.5b4, I'd hope to see different error. btw, are you still loading the .loc files from the same location?
- you should be able to leave HPS the same way you enter it - press "9"
- I guess cyan circles will never be in one place, but the "cyan" position (which is average of the last N average positions) should be the position with greatest possible accuracy
- you may get tsome idea of accuracy of the position(s) by looking at average hdop and number of satelites - these 2 numbers are shown in left-top corner, just bellow lat/lon
- I'll check the World Map issue with red coords
- enter waypoint manually prefills the text fields in the form with (WGS 84!) coordinates that corresponds to crosshair position; you may enter whatever (WGS 84) coords you want, in either DD MM or DD MM SS format.

In 0.9.5b4, I've changed filesystem browsing a bit for SXG75, anyone can try if it works? And if, by any chance, it is possible to browse and use files from memory card better?

Now I can finally load again .loc-files. Works for both, phone-fs ans card-fs - Thanks!
Yes, I was using the same .loc-files on the phone.

Oh. Thats's simple - and it even works.

OK. - Makes sense to me. - What is the value vor N? Can I toggle it (don't have to, just asking ... you see I'm curious!)

Since SXG75 doesn't provide Satellite Information the latter is sadly -1 for me. How do I interpred hdop-values?

OK & Thanks! - To me the world-map thing seems only, that the crosshair doesn't get moved to position and as a result coords are red.

I can browse and use files from memory card. That works now even for files in subdirectories (tried level 3 subdirs: /mmc-miscellaneous/abc/def/ghi.loc). - Cool.

But I get an error when I try to "Record Current" - Unfortunately the message appears after 1 Second again. My clue: It tries to save to "file:///E:/...." - This doesn't sound compatible with the SXG75s naming.

When I want to load a waypoint, the Directory list is as follows for me:

You may need to edit tracklogs directory (in Settings) , where waypoints are stored too; to something like "file:///mmc-misscellaneous/..."

Happy New Year and thanks for the new version 0.95betax. I tried all the maps I had probems beginning of December and now they are working 100% correct. (TM maps using a UTM grid) .

With all other maps I having problems now. These maps are generated with Map Calibrator and I am using the *.gmi cal-file. When loading these maps with 0.94 everything works fine but in 0.95betax it not able to show show the coordiantes on the map and to display the actual position. Hm what is the trick to get that work? All the maps which use OziExplorer *.map files are working very good. Here a example gmi file which is not working:

You may need to edit tracklogs directory (in Settings) , where waypoints are stored too; to something like "file:///mmc-misscellaneous/..."

Oh, Ok. - I had tracklogs set to never and hence the setting wasn't shown. Got that successful edited.

The good news first: I can now write files to SXG75. - However, only in the /fs directory of the BREW tree. This is due to your lentghy default filenames. SXG75 cannot handle filenames that exceed (incl. full path!) 30 characters. I don't know why, but this is a fact (see foum on SXG75.com - Might be related to the implemation of DRM).

Since mmc-miscellaneous is a default directory for stuff like waypoints and a subfolder "tb" would make sense, that leaves 8-12 charcters for the lognames. - I cannot say for shure, because the leading "mmc-" is not on the actual card - this seems to be a java-specific naming for the card.

The easiest way form my point of view would be to make the default-filename configurabe in settings.

I just got hold of the error message:

Code:

Failed to create GPX file file:///... java.io.IOException: [///... is not accessible for write

And since your filename is 43 characters long and I can save it in /fs it seems possible to handle some more than 30 chars. - The specified "30" chars was probably just an always "safe" length.
